Warnings
Contraindications
Hypersensitivity to any component of the vaccine, including rice protein
Cautions
There were 2 reports of anaphylaxis; monitor for signs and symptoms of hypersensitivity reactions following vaccination; appropriate medical treatment and supervision must be available in case of an anaphylactic event following administration
Vaccination may not protect all individuals; vaccinated individuals should continue to adhere to infection control practices to prevent Zaire ebolavirus infection and transmission
Safety and effectiveness have not been assessed in immunocompromised individuals; weigh the risk of vaccination in immunocompromised individuals against the risk of disease due to Zaire ebolavirus
Vaccine virus RNA has been detected by RT-PCR in blood, saliva, urine, and fluid from skin vesicles of vaccinated adults; transmission of vaccine virus is a theoretical possibility
Drug interaction overview
-
Interference with laboratory tests
- Following vaccination, individuals may test positive for anti-Ebola glycoprotein (GP) antibody and/or Ebola GP nucleic acid or antigens
- GP-based testing may have limited diagnostic value during period of vaccine viremia, in the presence of vaccine-derived Ebola GP, and following antibody response to the vaccine
Pregnancy & Lactation
Pregnancy
There are no adequate and well-controlled studies in pregnant women, and human data available from clinical trials are insufficient to establish the presence or absence of vaccine-associated risk during pregnancy
Consider the woman’s risk of exposure to Zaire ebolavirus before vaccination
Clinical considerations
- Fetal and neonatal outcomes are universally poor among pregnant women infected with Zaire ebolavirus
- Majority of such pregnancies end in miscarriage or stillbirth
- In pregnancies where live birth does occur, neonates generally do not survive
- Potential for transmission of the vaccine virus from mother to the fetus/neonate is unknown
Lactation
Human data are not available to assess the effects on milk production, its presence in breast milk, or its effects on the breastfed child
Consider developmental and health benefits of breastfeeding along with the mother’s clinical need and any potential adverse effects on the breastfed child or from the underlying maternal condition
For preventive vaccines, the underlying condition is susceptibility to disease prevented by the vaccine
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Recombinant vesicular stomatitis virus-Zaire ebolavirus (rVSV-ZEBOV; V920) is a replication-competent vaccine
Genetically engineered to express a glycoprotein from the Zaire ebolavirus to provoke a neutralizing immune response to the Ebola virus
Administration
IM Preparation
Thaw vial at room temperature until no visible ice is present; do not thaw vial in a refrigerator
Gently invert vial several times
Visually inspect for particulate matter and discoloration before use, vaccine is a colorless to slightly brownish-yellow liquid with no particulates visible
Use the vaccine immediately after thawing
Withdraw 1-mL dose from vial using a sterile needle and sterile syringe
IM Administration
Administer a 1-mL dose IM, preferably in the deltoid area of the nondominant arm
Discard unused portion
Storage
Unopened vials: Freeze at -80 to -60ºC (-112 to -76ºF) in the original carton to protect from light; do not thaw the vial in a refrigerator
